Dural

Dural was previously a human woman. Her name was Tsukikage and she was both Kage-Maru's mother and a Kunoichi. When the mysterious corporation J6 (Judgement6) noticed her exemplary fighting ability and resilient body, they captured her and used her as their prototype for their terrifying Dural project. Arming her body with various cybernetic enhancements and brainwashing, she became a cyborg, immune to feeling. Technically, she underwent roboticization, though this isn't directly stated in the games. She appears in both silver and gold skin, and also stone, black, and transparent in Virtua Fighter 5 (Dural also has her transparent costume in Virtua Fighter 4 and Virtua Fighter 4: Evolution), she is an excellent fighter in the right hands.

Since then, Kage has attempted to retrieve Tsukikage and restore her to her former self, finally succeeding in Virtua Fighter 3. However, he needed parts to keep her inhuman body operational, and when he retrieved them, she became even less human than before. Now Kage enters the 4th tournament to end his mother's suffering and return her to normal.

Meanwhile, the J6 corporation has their eyes on Sarah Bryant as the subject for their next Dural project.

During the Fourth World Fighting Tournament, J6 released their true model; however it was defeated. This drove J6 to kidnap Vanessa Lewis. Although Vanessa escaped, her combat data was captured and transferred into a new model: V-Dural.
J6 is now ready to test if their new advanced V-Dural is truly ready to defeat the world's best fighters - let the Fifth World Fighting Tournament begin...

Tsukikage is not the only Dural. In Virtua Fighter 4, her stage depicts thousands of Dural models encased in capsules. It is implied that the J6 corporation utilizes many subjects for transmogrifications, with Tsukikage merely being the first (albeit the most powerful). In several concept art CGI renditions for Virtua Fighter Kids, Dural-like robots of the "children" are seen.

Dural appeared in Beach Spikers, a beach volleyball game developed by Sega-AM2, in two teams; a Silver and Gold team and a Black team. They appear as opponents after completing the World Tour mode under certain conditions and if defeated, become playable.

Dural was playable in the Sega Saturn version of Virtua Fighter 2 through the use of a cheat code at the character select screen. The mnemonic cheat code was Down, Up, Right, A + Left, the first letters of which spelled the name DURAL.

In single-player VF2, the player fights Dural underwater, including slow-motion moves for both characters.

In Virtua Fighter Kids, one of the variations of the character featured her with a fishbowl for a head, complete with a fish swimming inside.

Dural is considered in some circles as a "bonus boss", as regardless of whether the player defeats Dural or not, the player gets the ending credits.

The name "Dural" was one of the code names for Sega's last video game console, the Sega Dreamcast.

In the Dojo training area of Virtua Fighter 5, and the experiment room in Virtua Fighter 4: Evolution, Dural is your opponent in command training.

In Virtua Fighter 2 for the Sega Saturn, if you finish the arcade mode without losing a match, after the ending credits there is a secret CGI cut scene where Tsukikage is shown breaking free out of the Dural armor.
